In her very person as a Jewish girl become the mother of the Messiah, Mary binds together, in a living and indissoluble way, the old and the new People of God, Israel and Christianity, synagogue and church. She is, as it were, the connecting link without which the Faith (as is happening today) runs the risk of losing its balance by either forsaking the New Testament for the Old or dispensing with the Old. In her, instead, we can live the unity of sacred Scripture in its entirety.From Rapporto Sulla Fede, a series of 1985 interviews given by Pope Benedict XVI to Vittorio Messori.
To use the very formulations of Vatican II, Mary is ‘figure,’ ‘image’ and ‘model’ of the Church. Beholding her the Church is shielded against the aforementioned masculinized model that views her as an instrument for a program of social–political action. In Mary, as figure and archetype, the Church again finds her own visage as Mother and cannot degenerate into the complexity of a party, an organization or a pressure group in the service of human interests, even the noblest. If Mary no longer finds a place in many theologies and ecclesiologies, the reason is obvious: they have reduced faith to an abstraction. And an abstraction does not need a Mother.
